To all whom it may concern Be it known that I. OsoAR H. BLOOM "owner, *a citizen of the United States, re-

. mechanisms.

siding at Crooks, in the county of Webster.

and State of Iowa, haveinvented. a certain new and useful Switch, ofwhich'the following is a specification The object of invention is to provide a combination electric switch of simple, durable'and inexpensive construction.

' More particularly, it is my object to pro-' vide an .electric switch board having a plurali of switch devices mounted thereon capa le of'being connected in different series or pluralities of series and provided with indicating. characters arranged adjacent to the switches so that theswitches in any series must be turned to a particular indicating character in order to complete a circuit, thereby enabling the operator to complete the circuit bya secret c'ombination,,which;

combination iscapable of a large number of variations.

Still a further object is to provide such a combination electric switch in which by the arrangemeent of the series above referred to, different circuits from the same source of electrical energyimay be created at different times, or at the same time through d f-' ferent series of switches.

'My' invention consists in certain details,

In the accompanying drawing gs, I: have used the reference numeral 10 to indicate 7 provide indicating characters 29;on the facev generally the support which forms the body or base of my" improvedswitch board. The support 10'is preferably made of suitable insulating material and is preferably provided on itslower surface with an annular circumferential flange 11 so constructed and arranged that if the board isilaid down upon a flat surface it will rest upon said flange and the main portion of the under I I Specification of Letters Patent.

Mounted in the support 10 a pluralityl, I of switches which are constructed as' --fol lows: In the upper surface of the board or pp 1 is a plurality'of holes w 1;

clearly shown in Fig. 3. Ihe board or sup:

portlO 1s providedwith a hole extending through it from the middle of each opening or hole 12. Extending through the'las't described hole and through the hole 12 and through-5 f the cylinder 15 is a bolt 16 having on'its" upper end the screw head '17 and; being;

screw threaded at 18 at its lower end 1 In the lower surface of the body 10- islan enlarged opening 19 in communicationwith' I 80 Mounted on the bolt 16, within the opening v each-of the openings through the .bodyy10.

The spring 20,- the washer 22 and the nut 21 serve to hold the bolt 16,',in.lpo'sitionf ora I holding the disk 13 firmly against the body '10., Extending'ffrom the bottom ofleach I hole 12 through the body 10 is'a plurality of conductor posts 23 preferably provided with enlarged heads 24 attheir upper ends and screw threaded. at their lower ends'and provided at their lower ends with nuts 25 and washers 26. bolts 23 form binding posts. Formed on The lower-"ends of the the cylinder 15 is a laterally extending arm 27; designed to engage one .of the 'boltsor osts 23. Mounted onithel'disk 13 is a andle28, wherebythe disk may be rotated. By moving the handle 28 around'the bolt 16 as a pivot, the arm 27 "may be "brought into contact with any of the bolts 23. Adjacent to each of the disks '13, 1 preferably 7 ing characters the arm 27 is solocated thatj it then engages a certain one of the bolts 23.

This may be the one practicallybeneath the indicating numeral or not Formed on the cylinder 15 is a laterally extending arm 30,-

indicated by the dotted, lines in Fig; 1 and so arranged with relation tothe arm 27 that" when. the arm 27 engages one of the bolts 23 the arm engages the head of another of said bolts. 'It will readily be seen that the bolts 23 may be arranged in any con- ,venient number at common distances, from each other and; that the arms27 and 30 may be arranged. at Various angles with relation I toeachv otherto correspond with'the position of the bolts 23. v .Mounted on the board 10, as shown 'in the drawings, are four binding posts 31-, 32,;33-and34. 'As will be seen from the description heretofore given and following, the number of said binding postsmay be increased as desired, 1 I have used the reference character 35 to indicate a suitable source. "of electrical energy. A. current conducting wire 36 con nectsthe'member 3,5 withthe binding post 31.. The binding post 31- is also connected with one of the binding posts on a bolt 23 as, for instance,at A. Suitably located are .coils 37 p and a-spark plug 38. A current co nducting wire39connects the member 35 withthe coil 37 and said coil is also connected by a current conductingwire 4:0 with the 7 binding post Suitablylocated'is a magneto 41 which is connected by a wire 42 with 1 the wire 39 'andz-by a wire e3 with the hind ing bolts 23 may be electrically connected in any I way-desired and thatthe circuit through. said bolts. may be, varied-to make a large,

The wire 44 connects thewire 40 and the binding post" 33. The bindingother, F and G with eachother, D and E with each other and C and A with each other, a circuit will be completed through wire 49, the switch 103, the wire 50, the switch 102, the wire 51, the switch 101, the

same way, as shown by the diagram, a c'ircuit. may be created by the wiringshown in 1 Fig. 2 through a difierent seriesof switches and. wires and through the magneto 41, As shown, each of thev circuits uses'the switch 100 but the handle 28 .must be turned to different positions for completing the different circuits, both of the circuits, including the ignition coil 37.

It will readily be seen that any number of combinations may be worked out and a circuit can be createdforoperating lights or for other purposes if desired. The system is shown simply for the purpose of illusv tration.
